Application filed December 12,1922, Serial No. 630,210, andin Great Britain November a, was.

The present invention relates to improvements in biscuit, bread or the like machinery operating upon a sheet of. plast c material quantities or the likem'aterial by stamps orother cutting devices, whereupon the reticulated sheet left after the removal of the cut-away portions ispassed to a collecting receptacle to be: again kneaded .upv and-formedjwith fresh dough'into ayshe'et of material'to be subsequently, acted 'uponby the cutting devices. I

. According'to the present invention, the

I waste dough in the form of the reticulated sheet isfolded one ora number of times upon itself to present the minimum surface the normal table or bed of the machine need only be a fraction of the width of this, and consequently does not interfere with the need room or light required on the main operating table or bed.

T18 invention is more particularly described with reference to the accompanying drawings (diagrammatic) in which Figure 1 is a side elevation of a biscuit making machine taken by way of example. F1gure 2 1s a correspondmg plan VIEW. Flgure 3 1s a detail of the delivery end on a somewhat'enlarged scale. i

Fig. 4 is a sectional view of the dough sheet as it passes on to the return conveyor. Dough is passed from a hopper 1 of the table 2, and then to the main operating bed of the machine 3, on which it is spread out as a thin sheet, and eventually passes outunder automatic cutters stampingout from the thin sheet of plastic material measured portions in the form of biscuits, buns or the like, these passing away to the delivery table whilst the waste in the form of a reticulated sheet 5 is passed upwards by means of a conveyor 6 over guide rollers 7 and 8, from which latter it is removed by a doctor or scraper 10 lying at the base of'a feed plate having curved side checks 9 adapted to fold over. the" reticulated sheet of dough one or more times .upon itself to fall eventually upona 'recei-vlng conveyor 11 which, as shown, needonly therefore bea fraction of the width ofthe main bed-plate 3 of-the machine. Consequently the advantage is obtained that a much less surface of the. dough is exposed in the operation of return- 1l1gl1l1lS' waste dough to a receiving receptacle 12 which is particularly important in a machine of the type illustrated in which the; waste from one machine passes back along the whole length of the machine to the front end of the machine to be mixed up with fresh dough and then'pass again-down the machine in a continuous "cycle. 7 The conveyor 6 returns from roller 8v over a gulde roller 9"" tothefront of the machine. It will alsoloe noticedthat owing to this lesser surface of the return sheet the return feed conveyor 11 can conveniently be arranged above the main bed of themachine,

and yet will not shroud the bed from light.

It is preferred that the returning conveyor 11 be driven at a higher rate of speedthan the delivery conveyor 6 wherebythe material 5'becomes split upinto a number of separate lumps which provide for a more even feed,'of the waste dough, backintoth'e ho per 1.

The conveyor delivering the return dough is arranged to swivel from side to side of the hopper so asto further allow" an even distribution of. returned dough into said hopper. v i 3 I declare that what I claim is 1. A method of handling waste dough or the like plastic material subject to deterioration. on exposure, in whicht-he waste dough in theform of a sheet is folded upon itself to give the minimum of surface, and which when so folded is split up into a plurality of small pieces. I i Y 2. A method of handling waste dough or the like plastic material subject to deterioration on exposure, in which the waste dough in the form of a sheet is folded upon itself to g ve the minimum surface and which when so folded is split up into a plurality of small pieces and when sosplit up is delivered at a greater rate of speed than the delivery, speed of the waste dough.

3. A machine for operating on plastic material subject to deterioration on exposure comprising means'for forming the plastic materlal into a thin sheet, means for removing measured quantities from said sheet, means for passmg the reticulated sheet remainder to folding devices, means tofold said sheet and means for removing said reticulated folded sheet to a storage hopper.

4;. A machine for operating on plastic ma-. terial subject to deterioration on exposure comprising means for forming the plastic material into a thin sheet, means for removing measured quantities from said sheet,

' means for passing the reticulated sheet re mainder to folding devices, means to fold sald sheet and conveylng means for receivmg said folded reticulated sheet, and means for driving said conveying means at a greater rate than the speed of delivery ofv said reticulated sheet.

5. A machine for operating on sheet plastic material comprising a bed cutting device operating on thesheet material on said bed, and a return conveyor above said bed of lesser width than said bed for returning the Waste reticulated material to the opposite end of the machine.

6. A machine for operating on Waste dough and the like plastic material in the form of reticulated sheets and subject to deterioration on exposure, comprising a folder'receiving the Waste dough in sheet form at a predetermined speed and discharging the waste dough in laterally folded sheet form of reduced exposed. surface, and a Withdrawal conveyor to remove said folded sheet from said folder at a speed greater than the speed of reception at said folder, whereby said folded sheet is split into a plurality of smali pieces. v

ate of'speed greater than the'speed of its reception at said folder, whereby said sheet is exposed to the atmosphere for but a short time, and is split into a plurality of small pieces.

8. A nachine for operating on dough and the like plastic material in the form of reticulated sheets and subject to deterioration on exposure, comprising means to-form said material into a sheet, means to remove portions from said sheet and reticulate the same, means to fold said reticulated sheet, said sheet travelling at a predetermined speed from said forming means through said foldin means, and means to return said folded sheet tosaid forming means at a rate 01 speed greater than the speed of movement from said forming means to said folding means and to split said sheet into a plurality of small pieces;

In Witness whereof, I have hereunto signed my name'this 24th day of November, 1923.
